Apliieenon ned July is, 188s.

To all Loli/07111 t may concern:

Be it known that I, CHARLES L. DEXTER, a citizen of 'the United Stat-es, and a resident of Philadelphia, Pennsylvania, have invented a Machine for Blanching Almonds, of which the ,following is a specification.

The object of my invention is to construct a simple'and eliicient machine for blanching alongitudinal section of myimproved blanching-machine. .of the same on the line l 2, Fig. 1. 'Fig 3 is Fig. :2 is atransverse section afdetached perspective vieiv of a number of the cleaning-bars; and Fig. 4 a detached view, drawn to an enlarged scale, of a pair ofblanching-rolls, showing their action upon an almond.'

A are a series of rolls having reduced portions ct a at each end forming journals. These journals are adapted to slotted boxes B B, on a suitableframe C. The rollsA are geared together by a train of pinions a at one end of the machine, the pinions being secured to the journals a. f

At one end of the machine is a roller A', having reduced portions forming journals in the same manner as the rollers A. This roller A has a pinion gearing with a train of rolls A, and is provided with a crank-handle K. The object of .extending this roll out to one end of the machine, is that the handle may be clear of the mechanism described hereinafter:

The rolls are coated With or made of rubber :or other flexible material and are adjustable toward and from each other try-means of setscrews b at each end of the bearings B, these -setfscrews bearing againstthe blocks @which rest against the journals of the rolls. turning these setscrews the rolls can moved toward'and from each other s o as to create more orless pressure on the skin of the almond to be blanc-hed.

It will be noticed that the rolls are divided into pairs, and I insert between each pair of senai Ne. 279,840.' (No model.)

rolls a triangular filling-piece, c, to prevent theV almonds re'sting in the spaces between the pairs of rolls.l

` D D are a series of cleaningbarS, connected together at their ends by endless 'chains or belts d. These cleaning-bars traverse the faces of the rolls in the direction of their length, as shown in Figs. land 2.

The chains pass over ksuitable sprocket- I Wheels E on a Vshaft E mounted in bearings in the frame of the machine and over suitable guide-rolls G, as shown inFig. 1, so that the cleaning-bars will pass over the rollsin 'the direction of .their length.' The vshaft E is geared to the journal o f the roll A through the medium of the bevel gear-Wheel e and bevelpinion e', so that it will be seen that While the rolls A travel at a comparatively high ratev of speed the cleaning-bars are moved slowly along the faces of the rolls.

The cleaningbarsmay be plain straight bars, if desired; but I prefer to make them in such a manner that they will conform to the contour of the rolls, as shown in Figs. 2 and 3, so that all the almonds will vbe removed from the machine. The projections p on the bars, as will be noticed, extend between those parts of the rolls where the blanching operation is carried on, the spaces between the pairs of rolls being occupied by the abovementioned fillingpieces Under each roll of the series 'is placed a scraping-blade s, resting against the faces of the rolls in order to remove any of the almond-skins or other matter which may adhere to the rolls. series of rolls maybe inclinedl slightly, in order toaid in the delivery of the blanched almonds.

I place over the rolls A a box M, which is provided with, a hopper N, and having a portion covered With'wire-gauze, glass, or other transparent material, so that the operation of the machine may be observed.

At thedelivery end of the machine'is a suitable box 0:, into which the blanched al-4 'r monds are conveyed bythe scraping-bars D. The operation of the 'machine is' as follows:

- The almonds are iii-st shelled and then scalded purpose ,of loos-- in the usual manner for the ening the skins. They are then fed into the mach-ine through the hopper, and, falling on The whole V from the almond vitis fed forward by the barsto the end of the machine and into the box or' receptacle ro The construction of the machine'may be different from that shown, tho main'ffeature of my invention being the series oi`ro1ls and the cleaning-bars traveling over the same, described. l

15 l have shown only three pairs of rolls 5 but it Will be understood that a greater or lees number of rolls maybe nseihand iuhe rolls may beA lengthened, in order to allow more time for the cleaning' or blanchiingr operation.

2o Although my niachineis especiaiijf mhiptod for the blanchir. or skinning.;l 1 fis, it will be understood that it may he 'o. i, f.. skinningor shelling.;1 other fruits or x'iloiable,

'l'. claim aa my invention 25 l. The combination, in an almond-blancaI ing machine, of one or more pairs of rollers having yielding snrfacee and mechanism for driving the same, with a cleaning bar or bars secured at each end and traveling over Said 3o rolls in. the direction oi their length, substantially as and for thc purpose set forth.

The combination, in a blanehingnm.`

chine, of one or more pairs ofblancl1ing-ro1l ers having yielding surfaces, with a series of traveling cleaning-bars secured at each end 35 and passing over the rolls in the direction of their length, said cleaning-bars being provided with project-ions so shaped as t-O conform to the contour 0f the rolls, Bnbtaniially as described. 4

3. The combination, in a blanchn maf chine, of a series of rolls having y @Ming surfaces, with scraping-bars bearing yagainst the faces of said rolls in order to remove the sinne that adhere tothe rolls, substantially 15 ae described.

4.. The combination, iu a blanching-machine, of a series of hlanching-rolls having yieldinn; Surfaces and mechanism for revolvin @aid ro1ls,with 'endlossbands to which. are 5o secured cl'caninppbars provided. with a' series A or" projections and adapted to remove the al-V inonde from ss'aid rolls, and an inclosing-box. harin, a hopper at one end and, with abonar the delivery ond of the machine forrocoiving 55 the almonds i'romsaid cleani1igbar5,Snbstanu tially described.

lo testimony whereof I have signed my nume to this specification in the presence of? two subscribing; wiinceees.
